Convert OGG to WAV
Short answer
Drop your OGG file into the converter below and download the WAV file. It runs in your browser with FFmpeg, for files up to 100 MB; nothing is uploaded. The file is re-encoded to 16-bit PCM audio in WAV. WAV keeps every sample of what it receives, but it cannot restore what OGG compression already removed, so the result sounds the same and is larger.
Maximum file size: 100 MB. The first conversion loads a ~30 MB converter engine, once per visit. Nothing is uploaded - conversion runs on your device.
Vorbis/Opus expanded to WAV - no quality gain. · Lossy re-encode · Browser-side via FFmpeg WASM - nothing uploaded.
Key takeaways
- The 159 KB OGG file became a 1.92 MB WAV file (+1107%), about 1536 kbps for the 10 second clip.
- The result holds: Audio: pcm_s16le 48000 Hz 2 ch.
- In your browser the same conversion of a 3 second clip took 0.04 seconds on the single-thread engine; natively, the 10 second clip took 0.08 seconds.
- Next to it: OGG to AAC (+3.0%), OGG to FLAC (+896%), OGG to M4A (+2.7%).
Measured: OGG to WAV
The converter's own ffmpeg arguments, run on a 10 second 1920 × 1080 excerpt of Big Buck Bunny (an animated film, not camera footage) saved in OGG. The browser column is the same arguments on the single-thread WebAssembly core with a 3 second excerpt, in a headless run; your device will differ. Results describe this clip and these encoders.
| Check | Result |
|---|---|
| Mode | Audio re-encoded |
| Input | OGG, 159 KB |
| Output | WAV, 1.92 MB (+1107%) |
| Output streams | Audio: pcm_s16le 48000 Hz 2 ch |
| Time, native, 10 s clip | 0.08 s |
| Time, browser engine, 3 s clip | 0.04 s |
A re-encode decodes and encodes every frame or sample, so the time grows with the length of the file.
OGG vs WAV
| OGG | WAV | |
|---|---|---|
| Full name | Ogg (Xiph.Org) | Waveform Audio File Format |
| What is inside | Vorbis audio, sometimes Opus or FLAC | Uncompressed PCM audio |
| Compression | Lossy | Uncompressed |
| Best for | Open-source software and games | Editing and mastering, where every sample matters; very large files |
What you get
16-bit PCM audio in WAV. Vorbis/Opus expanded to WAV - no quality gain.
Planning a bigger file
These are estimates scaled up from the 10 second clip. Real files differ with content, resolution and bitrate, so treat them as an order of magnitude, not a promise.
| Length of the video or recording | Input size (like ours) | WAV size | Time in your browser |
|---|---|---|---|
| 1 minute | 955 KB | 11.52 MB | 1 seconds |
| 10 minutes | 9.55 MB | 115.20 MB | 8 seconds |
| 1 hour | 57.29 MB | 691.23 MB | 49 seconds |
An OGG file of this kind reaches the 100 MB limit of the converter after about 110 minutes; converting it would take roughly 1.5 minutes on the single-thread engine, and the WAV would be about 1265.23 MB.

Choosing WAV
WAV: Waveform Audio File Format. Editing and mastering, where every sample matters; very large files. OGG: Ogg (Xiph.Org). Open-source software and games.
- Keep your original: a re-encode is a copy of a copy.
- If the destination states the format it accepts, use that and nothing else.
Questions people ask
Is this OGG to WAV converter free and private?
Yes. It is free, needs no account and runs entirely in your browser, so the file never leaves your device.
Will converting OGG to WAV reduce quality?
WAV adds no loss of its own, but quality cannot be better than the OGG you start from.
Is there a file size limit?
Files up to 100 MB. The first conversion downloads a converter engine of about 30 MB once per visit; larger files are better handled by a desktop app such as HandBrake or FFmpeg.
How do I convert OGG to WAV?
Choose the file in the converter above and download the WAV. It runs in your browser with no upload.
Will converting OGG to WAV reduce quality?
WAV adds no loss of its own. Keep the original file.
Why did the file size change by +1107%?
The target codec and settings decide the size. This 10 second clip came out at 1.92 MB, about 1536 kbps.
How long does it take?
A 3 second clip took 0.04 seconds in the browser engine in our test; time grows with the length of the file.
How long will an OGG file of 100 MB take?
At the speed we measured in the browser engine, about 1.5 minutes for a file like our clip. Your device and the content will change it.
Is my file uploaded?
No. The conversion runs in your browser.
Is there a size limit?
Files up to 100 MB. The first conversion downloads a converter engine of about 30 MB once per visit.
